Title: Appatus for recording image
Inventor: YOSHIDA NOBUAKI
IPC: B41J2/065
Filed: 1980-10-07
Abstract: PURPOSE: To provide an apparatus wherein each of styluses has at least one edge in the longitudinal direction so that the bulged state of magnetic fluid is kept most suitable at all times, and in every recording such as high speed recording, etc. stabilized recording quality can be obtained.  
     CONSTITUTION: A plurality of styluses 1 having a quadrilateral cross section and made of a magnetic material are arranged uner a magnet 10, and the upper surface thereof extends beyond the magnet 10. The lines of magnetic forces go from the N pole via the stylus 1 to a slanted surface 11 and the S pole. Since the center of the side surface of the stylus 1 is a plane surface, and there are less lines of the magnetic forces there, that means there is less magnetic force, the adhesion of the magnetic fluid in the non-recording state will become the state as shown by dotted line, while since at the edge of the end of the stylus there are many lines of magnetic forces due to the edge effect, that means there is large magnetic force, the  amount of the adhesion of the magnetic ink is large there as shown by dotted line  in the nonrecording state. In the recording state, even when the magnetic fluid at  the tip of the stylus has been consumed, as the magnetic force distributed to the tip  part of the side face is strong, the magnetic fluid will flow from the slanted surface  11 to the side, and the bulge will appear again.

Title: Exhaust gas purifier for diesel engine
Inventor: SAKURAI SHIGERU
IPC: F01N3/02
Filed: 1980-10-09
Abstract: PURPOSE:To make it possible to reform a filter for trapping carbon particles even in engine operation by shutting-off a valve positioned downstream of the filter, in a predetermined period, for raising a temperature in the inside of the filter when the engine operated under the intermediate load. CONSTITUTION:Exhaust gas discharged from an engine 1 and containing carbon particles is purified through a filter 4 made of ceramic or the like, and is discharged to the atmosphere. When the filter 4 is blocked, backpressure is increased, which is detected by a pressure sensor 12 disposed upstream of the filter 4. Therefore, the sensor 12 produces a signal S2. Further, when a detector 13 detects the condition that the engine is operated under the intermediate load, it produces a signal S3. Therefore, if both signals S2, S3 are applied to a controller 11 which, therefore, generates a signal S1 during the period that is set by a timer 14 within a range 1-10sec, a passage communicating to an operating chamber 7b in a diaphragm unit 7 actuating a shut-off valve 5 which is disposed in an exhaust pipe downstream of the filter 7, is diverted to communicate with a negative pressure source 10 by a 3-way valve 5 which switches the passage opened to the atmosphere, by receiving the S1, so as to be in communication with the negative pressure source. Thereby the valve 5 is closed to raise a temperature in the inside of the filter, resulting in that carbon particles are burnt, thereby to reform the filter.
